Not to mention that '@.*' is exactly equivalent to '@'.

Or that grep would be far more suitable, viz. 'grep @ list.txt'.

Perl, of course, is always an option:

perl -e 'open LIST, "<list.txt"; @list = <LIST>; close LIST; @email =
grep (/\@/, @list); print foreach @email'

invariable experience that the company of a mere child is infinitely
preferable to that of a mere adult.
